Drives the beam in a circular path. Includes modulation for sweeping the beam over the entire surface of the crucible. Fixed 200 Hz circular frequency with a variable 5 to 50 Hz modulation. Rack mountable and includes all connecting cables.

Features:

• Circular output
• Current regulated
• Amplitude modulated
• High 200 Hz frequency
• ±operation

With the model XYCS circular sweeper, the entire surface of the e-Gun crucible can be swept, yielding a uniform melt with no discernible hot spots across the surface.

The XYCS sweeper supplies a sine wave drive to the longitudinal and lateral coils of electron beams guns. These waves are separated by 90 electrical degrees. As a result, the electron beam is driven in a circular pattern across the surface of the melt.

By adjusting the amplitude of the longitudinal and lateral sine waves, the diameter of the circle is changed. A triangular-shaped modulating wave is applied to the amplitude control, and the resulting beam expands and retracts in a concentric, linear manner.
